1. Andrographis: Shorten Summer Colds Andrographis does a great job of relieving upper-respiratory infections, such as colds or sinusitis, says new research. A study in the journal Phytomedicine reported that the herb eased symptoms such as fatigue, sleeplessness, sore throat, and runny nose up to 90%.
Maximize the benefits: Lee and the Graedons recommend Kan Jang (available at ProActive BioProducts), an herbal extract produced by the Swedish Herbal Institute and used in several of the trials.

2. Sea Buckthorn: Reverse vaginal dryness Sea buckthorn (Hippophae rhamnoides) is very effective for hydrating mucous membranes and alleviating vaginal dryness. It contains palmitoleic acid, a fatty acid found in human skin that helps moisturize and heal it.
Maximize the benefits: Lee suggests up to four capsules a day of Supercritical Omega 7, a sea buckthorn supplement by New Chapter. It’s available at health food stores.

3. Kudzu: Curb problem drinking A group of moderately heavy drinkers in their 20s voluntarily cut their beer consumption in half after taking capsules containing the Chinese herb (also called Pueraria lobata) for a week, according to a study published in Alcoholism: Clinical and Experimental Research. Researchers say the kudzu more quickly allows alcohol to get to the part of the brain that tells you that you’ve had enough.
Maximize the benefits: Participants took capsules with 500 mg of kudzu extract three times daily.
